Title: Improvements in or relating to permanent magnet brakes or clutches
IPC: F16D13/40
Filed: 1951-06-01
Abstract: 721,748. Magnetic brakes and couplings. BAERMANN, M. June 1, 1951 [June 2, 1950; June 22, 1950; Feb. 12, 1951; Feb. 14, 1951; May 19, 1951], No. 13048/51. Class 35. [Also in Groups XXIV and XXXIV] An eddy-current brake, Fig. 5, comprises two rotatable discs 19 of ferro-magnetic material and having copper rings 21, secured to a shaft 18 to be braked, and plates 22 of non-magnetic material secured between the discs 19 by bolts 23 to a stationary part of the machine and provided with pole pieces 25, Fig. 6. Permanent magnets 29 of opposite adjacent polarities as shown are secured in a disc 26 and may be rotated relatively to the pole pieces 25 by movement of a handle 30, so that when the magnets lie directly opposite the poles 25 the brake is operative. In this position the flux from the magnets passes from the N poles through the pole pieces to the S poles by way of the air gaps and copper rings. In the inoperative position the magnets lie with their poles between the pole pieces so that the flux is shunted without passing through the copper rings. In another embodiment, Fig. 9, a brake drum 40 of ferro-magnetic material lined with a copper ring 41 is spaced by an air gap 42 from a disc 39 carrying magnets 36, ferro-magnetic bodies 37 which may form a closed path for the flux, and soft iron pole pieces 38. The magnets may be rotated by links 44 engaging a slotted rotatable disc 47. In a further embodiment two discs 68, 69 of non- magnetic material are mounted on a stationary element 67 and carry magnets 70 polarized as shown in Figs. 15 and 17. The discs may be relatively rotated through a gear wheel 71 so that the magnets may be brought into contact with one another in the inoperative position, whilst in the operative position their flux passes through a thin pole piece 75 and through a copper disc 76 to a brake drum 77. In yet another embodiment magnets are brought into contact by tilting so that the flux is shunted away from the brake drum. A magnetic fluid coupling, Figs. 21 and 22, comprises a driven shaft 106 which supports a ferro-magnetic housing 107 containing a mixture 108 of oil and iron powder. A disc 111 also of ferro-magnetic material is mounted on a shaft 110 so that in the operative position, Fig. 22, an annular magnet 113 enters the housing 107 and magnetizes the oil and powder to form a more or less rigid coupling. Specification 562,622 is referred to. Reference has been directed by the Comptroller to Specification 649,553, [Group XXXIV].

Title: Improvements relating to railway signalling systems
IPC: B61L23/16
Filed: 1936-05-12
Abstract: 475,101. Railway signalling systems. WOODFORDE, J., and WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. May 12, 1936, No. 13437. [Class 105] A railway signalling system operated by coded rail current in accordance with ahead traffic conditions is provided in special block sections, for instance where points are located, with means independent of traffic conditions for preventing the appearance of any other signal than a stop signal at such section. In the arrangement shown the signal SA for section AT is subject to control by ahead traffic conditions which determine the particular code current (75 or 120 interruptions per minute) applied to the track rails and therefore the particular response of the decoding apparatus consisting of a code-following relay ATCR with a decoding unit ADT which with either code energizes a relay ATR (serving therefore as a track relay) and with 120 code energizes a unit ADU which can energize a relay ADR (serving therefore as a " distant " relay). An additional control by a king lever or by a signal lever is however necessary before a clear or caution signal can be given. Closure of the king lever contact AK with the signal lever AL closing its reverse contact R causes a " home " relay AHR to be energized over a front contact of the " track " relay ATR. Contacts of the home and distant relays AHR, ADR then select the particular signal, clear, caution, or danger, according to the head conditions and the system acts purely automatically. The operator in the cabin AC can stop the automatic working by opening the king lever contact AK and thereafter for each train it is necessary to restore the signal lever AL to normal and subsequently put it to reverse before the signal can show a clear or caution aspect. The restoration of the signal lever AL to normal picks up a stick relay ASR the front contact of which then energizes the home relay AHR (when the signal lever is put at reverse). Entry of a train drops the relay ATR which drops the stick relay ASR and the home relay AHR. Caution code is applied to the rear section CT only if the danger-signal lamp of the occupied section AT is alight and causing a relay ALR to be energized. If the points are in a " cut " section then when the rear " cut " is free sustained uncoded current is supplied to such rear cut and the sustained energization of the code-following relay gives an indication of such rear cut being free.

Abstract: 918,214. Bending steel mesh. BAU-STAHLGEWEBE G.m.b.H. April 17, 1961 [April 23, 1960], No. 13713/61. Class 83 (4). Steel rod mesh 9, 9<SP>1</SP>, Figs. 1, 2 and 3, for use in reinforced concrete, is bent by means of a tool member 2, 3 which in its inoperative position is arranged with an edge parallel to and adjoining an edge of a supporting beam 1 on which the mesh is positioned by means of bending dies 4, 4<SP>1</SP> projecting transversely from the edge of the tool member with their aligning axis x-x substantially parallel to that edge and provided with bayonet-like lateral recesses receiving the rods of the mesh. Bending is effected by rotating the member 2, 3 by means of handles 8 about an axis coincident with the aligning axis of the dies. The tool member consists of a plate 3 secured by means of screws 7 to an L-shaped beam 2 which is connected through cranks 2a, 2b to the handles 8 which are rotatably journalled in support 10 on which the beam 1 rests. The dies consist of legshaped members 5 terminating in cylindrical portions 4, 4<SP>1</SP>. For bending the mesh, the dies are made to protrude through the open spaces between the rods 9, 9<SP>1</SP> and the mesh is shifted laterally so as to cause the rods 9 to be inserted in the die recesses where they are clamped during bending. The beam 2 together with the plate 3 are then rotated counterclockwise through 195 degrees, Fig. 6, by means of the handles 8 so as to bend the rods 9 around the dies 4. After release of the bending tool the bent mesh assumes a final bending angle of 180 degrees. The dies 4, 4<SP>1</SP> may be interchanged by removing the screws 7 and rotating the plate 3 when in a horizontal position through 180 degrees about its pivot 6. The dies 4, 4<SP>1</SP> may have identical or different spacings and shapes. In a modification, the plate 3 consists of a number of juxtaposed components each removably and rotatably mounted on the beam 2 and the dies may have different spacings and may vary in diameter on different sides of a component or from component to component. In a further modification, the dies of a single plate may be individually exchangeable. Examples of cross-sections of various mesh structures obtained are described.
